“…Subretinal cysts may produce vasculitis, chorioretinitis and macular oedema, but they rarely occur in eyelid, subconjuntiva, optic canal and lacrimal gland. 6 Orbital cystcercosis, outside the eyeball, involves extraocular muscles leading to myositis and ocular motility problems.…”

Cysticercosis is the most common parasitic infestation affecting the central nervous system (CNS). It is well recognised worldwide as neurocysticercosis (NCC). Due to the diverse clinical spectrum, NCC poses a complex diagnostic and treatment dilemma. However, new diagnostic imaging and effective antiparasitic drugs have uncovered silent cases of NCC with unusual presentations, reducing the rate of morbidity and mortality.

“…It has been described to present with a picture of neuroretinitis and has been previously managed with both conservative and surgical therapy. [1][2][3][4][5][6][7] The cases described in the literature have had isolated optic nerve involvement. The present case report describes a known case of neurocysticercosis with a secondary optic nerve involvement.…”

Minimally Invasive Bone-Saving Orbitotomy for Removal of Optic Nerve Cysticercosis

A 32-year-old man previously being managed for multiple neurocysticercosis presented with a reduction in vision and pain on eye movement. Fundus examination revealed disc edema with venous dilatation. MRI showed a localized hypointensity on T1 weighted images and hyperintensity on T2 weighted images suggestive of a cyst in the optic nerve sheath. Medical therapy with albendazole and steroids did not improve vision. Surgical removal of the cyst was achieved by a modified lateral orbital exploration using a lateral canthal incision without bone removal, with full recovery of vision. Histopathological examination confirmed cysticercosis.

“…On surveying the literature on myocysticercosis, we found that the commonest muscle reported to date is the medial rectus (42%), followed by superior rectus (18%), lateral rectus (15%), inferior rectus (13%), superior oblique (5%), levator palpebral superioris (5%) and inferior oblique (1%) 6,23,26,28,34−41,43,62−65 . The subconjunctival space is another common site, 6,21,24,33,38 followed by the eyelid, 6,12,21,22,27,40,66,67 optic nerve, 5−11 retro‐orbital space 6,12,28,35 and lacrimal gland 12,29 . In all cases of eyelid cysticercosis so far recorded, the cyst was found to be lodged in the subcutaneous tissue, except in one case, where it lodged in the orbicularis oculi muscle 12 .…”

“…Following these reports, curiosity about ophthalmic cysticercosis increased, leading to the discovery of Cysticercus at different locations within the eyeball, orbit and adnexa. The first case of optic nerve cysticercosis was published in 1962, 5 following which six more cases of optic nerve cysticercosis have been reported in world literature 6−11 . Lodgement of C. cellulosae in the lacrimal gland and orbicularis oculi muscle was first reported after histopathological confirmation in 1979 12 …”

Orbital and adnexal cysticercosis is emerging as a far commoner disease than previously considered, both in endemic and nonendemic areas of cysticercosis. A review of the literature on orbital and adnexal cysticercosis found that it has a predilection for children and young adults with no definite sex predilection. The extraocular muscle form is the commonest type of orbital and adnexal cysticercosis. Lodgement of cysts in the subconjunctival space is another common site, followed by the eyelid, optic nerve, retro-orbital space and lacrimal gland. Association of orbital cysticercosis with systemic cysticercosis is quite rare. The clinical manifestations of orbital or adnexal cysticercosis are entirely different and depend on the location, size, relation to adjacent structures and stage of evolution of the cyst. Diagnosis of cysticercosis is based mainly on orbital imaging because of its highly specific appearance. Tissue diagnosis is not essential for initiating treatment. Medical therapy is the recommended treatment for the extraocular muscle form and retro-orbital cysticer-cosis. Surgical removal is advocated for subconjunctival and eyelid cysticercosis. Because of the limited number of cases of optic nerve and lacrimal gland cysticercosis, their treatment is controversial.
